I just installed some MB Quart 4" seperates in front and 4" 2 ways in the
back a/c cabinet with an Alpine MiniDisk player in the dash and a bazooka 8"
tube under the driver side rear seat.  It only took me a couple of hours to
do it and it sounds great.  I looked around for along time for a head unit
that wasn't too long for my vanagon dash.  I had a sony and I had to jam it
in to get it to fit, skipped like crazy and overheated right away.  The
Alpine has is under 6" deep if I remember, I actually have some air between
the end of the deck and the duct in the dash.  I hated cutting holes in my
drivers door panels for the tweets but it came out clean and it was worth
it!

I have a 85 VanagonGL with factory speakers placed in the front of each
door.  I want to upgrade but the speaker cover doesnt want to come
  Any ideas from someone whos been
through it??
thanks
